No, actually, that's part of it, because some DMs, when they are bored, will start to wonder about the rules, and whether they need the or if they work as they want them to work, or, if the next campaign will need to have something modified to suit its "flavor." I know every game I play has something different about it. Obviously the original poster engaged in the same activity, because he wanted to see how far the system would go... that's pretty much a test of the rules-heaviness, checking to see if it could support such a creation.
I'm not even arguing for rules-lite. I don't care how someone else plays. Or, what they play.
I'm just explaining, in a tangental way, why I'd go so far out of my way to do something insane like creating a 14,000th level character. At that point, rules are useless (well, maybe bot completely, but they are for me.)
Can't we have fun?
